Introduction

Lao also Laotian, is the official language of Laos. It is a tonal language of the Tai family, and is so closely related to the Isan language of the northeast region of Thailand that the two are often classed as one language. The writing system of Lao is an abugida (a writing system composed of signs denoting consonants with an inherent following vowel) and is closely related to the writing system used in Thai.
